Bone marrow aspiration is one of the most common tests used in hematology to make a definitive diagnosis of most blood disorders and, at the same time, to evaluate the effectiveness of treatment for blood disorders. The cost of a bone marrow aspiration test, if it is simply the cost of the procedure, anesthesia and the cost of the puncture kit, is usually around$200. However, what really costs a lot is the related laboratory tests done after the bone marrow is extracted. Because with the development of modern medicine, the diagnosis of blood disorders is more refined, and in addition to the conventional morphological examination, cytogenetic, chromosomal and molecular biology examinations are also required, which generally cost more, such as chromosomal examination costs about 600 RMB, immunological examination is about 1200-2000 RMB, and bone marrow matching examination is generally about 2000 RMB. Therefore, the cost of bone marrow aspiration test is different for different diseases. Generally, the bone marrow aspiration test for leukemia patients is around 4,500-5,000 RMB, but if genetic sequencing, etc. is required, the cost is higher. Patients with remittent disease and myeloma cost less, usually at the level of about$2000-3000.
